Frequently Asked Questions
The frequency conversion winding allows the motor to operate stably between 1Hz and 50Hz, which enables precise control of water flow, significantly reduces energy waste, and prevents motor burnout by adapting to actual well conditions.
While designed for clean water, the 150QJB includes a sand ring and dual oil seals to protect the motor. However, it is strictly prohibited to pump sediment or turbid water from new wells to avoid premature damage.
The pump must be fully immersed in water, with a penetration depth not exceeding 70m and a distance of at least 3m from the bottom of the well. It must be installed vertically with proper external overload protection.
To prevent freeze damage, all water must be drained from the motor cavity before storage. Store the unit indoors in a non-corrosive environment with temperatures below 40°C.
Immediate shutdown is required. Excessive vibration can be caused by the pump running against the well wall, improper installation, or air in the system. Check the centering and installation depth.
It is recommended to perform full disassembly and maintenance every year of operation, or if the pump has been submerged for two years, to replace wearing parts like impellers and sealing rings.
